Determination of Technical and Functional Properties of The Homemade Olive Oil Extraction Plant

This study has been conducted for the purpose of evaluating technical qualities ofhomemade olive oil production line. Memecik type of olive is used as the main material in thisstudy. Energetic parameters of units and the factors affecting the performance of the plant wereinvestigated. The specific energy consumption (SEC) values were 68.33×10-3 and 8.857×10-3 kWh/kg in terms of gross (EECg) and net (EECn) electric energy consumption, respectively. Also,the ratio of EECn to EECg which was 11.14 % defined as the percentage of productive energy (PE).The motors belonging to olive conveyor in defoliation-washing system (DWS) and decanter andpomace discharge pump in olive oil extraction system (OOES) were inefficient according to powerutilization (%) values. Accumulation of product on the internal surface of the malaxer caused tomaximum non-repeatable product loss (NRPL) of 3.07 %. However, in terms of repeatable productloss (RPL) 0.38 % of the olives and 2.74 % of the oil was wasted through the process. In addition,olive mill waste water (OMWW), olive oil extraction efficiency and average particle size of crushedolive stones were stated as 1.51 m3, 89.57 % and 3.249 mm respectively. Process temperature,which was 27oC max., degree of free acid, the number of peroxide and UV absorption amountplace the produced olive oil into the category of ‘Virgin Olive Oil’ or ‘First Cold Pressed Olive Oil’according to both national and international standards.
